\(\bullet \)  MultiTHUMOS [1]} has the same set of videos as in THUMOS14 [2]}, but it extends the latter from 20 action classes with \(0.3\)  labels per frame to 65 classes with \(1.5\)  labels per frame. Also, the average number of distinct action classes in a video is \(10.5\)  (compared to \(1.1\)  in THUMOS14), making it a more challenging multi-label dataset. Also, maximum number of distinct actions per video is 25.
